Moin Mein Kia Cee ́d SW Kombi (platform ED) 1.4L Gasoline DOHC 16V EZ082011 seems to lose cooling fluid. I would like to go to the workshop soon. About 4 weeks ago I filled it up with a little water, because it was just under minimum. Today I saw that the balance tank is almost completely empty. Down in the engine compartment it is also a little damp, but I am not sure whether it is oil or cooling liquid or maybe something else. If I now only W Asser refill, the water content would be quite high. So I wanted to mix it with coolant. Unfortunately, neither on the balance tank, nor in the manual, which coolant belongs in -.- Can any of you help me?
